I'd love to see this extension taken one step further and allow customers to access their online address books from Hotmail, Google, Yahoo, Facebook, Etc.

If they are presented with all their contacts in one place, then they can send an email to the masses, all at once. Plus, the easier you make it for them, the more likely they will a) use it in the first place and b) send it to a TON of friends vs. if they had to type each email address out, one by one.

-->Plus, they'll want to send a lot since the whole idea of this extension is to reward the customer for referrals!
